[K8N SLI Platinum] Issue with Aggressive timing

Hi,
  System doesn't boot up if "Aggressive timing" is enabled in the BIOS, somehow it ends up searching for RAID configuration and hangs up.
-Thanks

Why must used the Agressive timing? I'll disable it in order for me to OCed it successful but when I enable it with minimal I'll get BSOD or sometimes not even boot so I need to either disable the it or reset the Bios again.  Gd luck.

  • MSI K8N SLI Platinum crashed with my videocard

    Hi. I don't speak english very vell, so sorry  
    A bought an MSI K8N SLI Platinum mainboard, 7800 GTX Videocard and I don't know use it with NON SLI mode   If the SLI card there in NON-SLI mode, my pc isn't run. Just black screen, and the D-Bracket is show, that the booting is stopped in memory-control (second LED is red.) If I turn my SLI card for SLI mode, accordingly the PCI-E bus is 8x and my PC is run.
    My problem is that, that I don't know run my pc in PCI-E x16
    I tried 6 BIOS, but always was this is the problem
    Ha van itt magyar ember, akkor magyarul a probléma:D:
    Szóval van egy ilyen lapom, de nem tom használni 7800 GTX-el. Egyszerűen nem tudom használni non sli módba, a kép mindig fekete és memória-ellenőrzésnél megáll   sli módban meg megy a gép, de csak 8x-os üzemmódba. ugyan ez a hiba egy 6600 gt-vel is. Szóval helllllp

    First, search the internet for a free translater program and cut n paste.  Second, you need to place the graphics card in the pcie slot next to the cpu.  Third, you need to make sure the SLI switch card is placed "non-sli" with the arrow pointed towards the graphics card.  Finally, you need to make sure your SLI switch card is fully in place so the copper teeth dont show (I made that mistake and my rig didnt boot either).  Just my 2 cents.   
    1st -- ok 
    2nd - the video card is there next to the cpu in 1st PCI-E bus
    3rd -- the SLI switch card is placed non-sli with the arrow pointed towards the graphics card.
    fin --- well, i have no idea about this, 'couse after i've removed the card, i could not push it back to its place fully anymore, so the copper teeth show up. I also tried to force it with a screwdriver, but it didn't work. but i can turn on the card holder

  • Is the Hiper Type- R 580 modular PSU compatible with MSI K8N SLI Platinum?

    Hey guys, i just recently bought a Hiper Type R 580w PSU after my old PSU went bad.
    I installed the new PSU a few hours ago and came across a problem, nothing shows up on screen.
    When i turn on the computer, the green light is constantly on including my dvd/rw light.
    I double checked everything were connected properly and everything seemed to be connected properly.
    The cpu's fan are running properly including the graphics cards and the case's fan but i can't pinpoint whats causing the the green activity light to light constantly including the dvd/rw.
    I also tried resetting CMOS but it didn't fix the problem.
    So now i'm starting to wonder if it's to do with compatibility issues between the Hiper Type R PSU and my K8N SLI Platinum motherboard.
    So i just wanted to know if the Hiper Type R 580 PSU is compatible with the K8N SLI platinum?
    I would grately appreciate any assistance.

    In short no.
    The Hiper Type- R 580 does NOT have a -5V supply line
    Although the -5V requirement has been removed from some MSI designs, the MSI page for the K8N SLI Platinum http://msicomputer.co.uk/Products.aspx?product_id=703525&cat_id=77 states:

    • These two connectors (JPWR1 & JPWR2) connect to the ATX power supply and have to work together to ensure stable operation of the mainboard.
    • Power supply of 450 watts (and above) is highly recommeded for system stability.
    • For ATX 12V power connection, it should be greater than 18A.
    • For this model, you must use the power supply that with a -5V pin supply.

  • K8N SLi Platinum USB keyboard boot issues

    Hello, I have a K8N SLi Platinum connected via an Aten US221 USB switch (http://www.aten-usa.com/?product&cat=804&Item=US221) and a Kensington USB hub to a Logitech MX518 mouse and a Logitech multimedia pro keyboard. I use this to connect the same two input devices to two computers and toggle. Previously I used a keyboard to each, with a Dell PS/2 used on the MSI motherboard.
    The problem is that the MSI motherboard fails to detect the keyboard every other boot or so. It doesn't matter if I unplug the Aten switch, the USB hub or even connect it directly to the USB root hub. The only thing that solves it to restart the MSI computer over and over until it decides to start working. And I need the keyboard since I have a bootloader (GRUB) that I select which OS to boot with. The switch and keyboard works without a hitch on an older Dell computer which is also connected in tandem.
    Since I need both mouse and keyboard on a single wire I cannot use a USB-to-PS/2 connector. I've found several posts here which suggests this motherboard is buggy, if that's the case shouldn't MSI issue some sort of BIOS patch?
    Sincerely, Martin "xarragon" Persson

    Might work.
    I don't like the inconsistency you describe: working sometimes and after a lot of reboots. Would you say your system parts, please. Troubleshooting this in your end must include finding a situation where it never works, and when it always work. For example, if you don't have the mouse connected at all, if you don't use the hub, etc.
    Not saying motherboards can't be damaged, specially port end, but the hub thing is a more likely culprit.

  • [Resolved] No boot with K8N sli Platinum & AMD 64 X2 3800+

    Hye,
    I've received these new stuff last night (everything is good until here) :
    - Antec Sonata II 450W
    - MB MSI K8N SLI Platinum
    - Proc. AMD 64 X2 3800+
    - GC Sapphire X800 XL 256Mo
    I've assembled all and turned it on... No bip... but all the fans are turning... and the screen says "No signal" and becomes black ( and me    )
    Can someone help me? Please?
    On the MSI site, I also found this :
    http://www.msi.com.tw/program/products/mainboard/mbd/pro_mbd_cpu_support_detail.php?UID=641&kind=1
    Maybe the proc. and the Motherboard are not compatible? Has someone already tried this combinaison (MB+Proc.)?
    My Thanks in advance.

    I will ask the sellers if they can update the Mobo for me.
    But with the last version of the bios, will the mobo accept the dual-core with this proc. AMD 64 X2 3800+?
    And if it's not possible I'll change the mobo.
    Thanks .................................. again.
    Pretty much any SLI motherboard supports the X2 3800. MSI is just really pathetic sometimes. So, I had the Abit AN8 SLI before and their latest BIOS (17) supports all X2 CPUs. But Im sure most other brands support them too.

  • Problems with older PCI-Videocards on K8N SLI Platinum ??

    Hi there,
    i just recieved my K8N SLI Platinum (without NEO) yesterday. Unfortunatly my new PCIe-Videocard isn't here yet,
    so i just built my rig with an old S3 Trio64 to install Windows etc. and to have at least my PC for some surfing and so on...
    The problem is:
    The Card is marked with an ! in the device-manager. It says the card couldn't get its required resources, and that i'd have to
    disable some other device of the system first to fully use the videocard. I checked for IRQ's, but the card has an exclusive one.
    I put it in the second (middle) PCI-Slot on the board. Due to that error, the drivers are not installed correctly and the performance
    of the display is ... well its even to slow for scrolling pages while surfing ... thats realy anoying, and my PCIe-card will not be here
    until the end of next week 
    I even manged to get another old PCI-dinosaur, but with no luck. The same Problem persists. So i think it's some problem with
    the board or some iossettings. The only thing regarding display in the bios was the PCIe / PCI switch which is correctly set to PCI.
    So if anyone knows how to get an old PCI-card running in that board, please help me
    [ApoC]

    Well,
    "f***ing up" the OS is not a problem, i got a GHOST of my perfectly fresh & clean OS.
    I have disabled:
    both SATA-Controllers (still running on good old ATA Samsung SpinPoint P80)
    the FireWire-Controller (which is shown in Windows anyways  )
    I changed the videocard from PCI 2 to PCI 1, with the only result that it shares IRQ with the OnBoard-Soundblaster in slot1.
    In slot2 it gets an exclusive IRQ. The problem is, i can't even see what resources are making trouble since Windows doesn't
    show any information in the cards resource-infos but that it ain't working (say what?)   
    *sigh*
    [ApoC]

    I remember problems with the APIC-Mode on many nForce-2 Boards. Could this still be a problem? Any infos on that matter yet?

    Maybe i need to add more electric power for my memorys. The spec says 2.80 volt on 250 mhz but i start to suspect that this is just an minimum requirment, maybe i need more than 3.0 v to operate the memorys on high performance(beyond 230 fsb), but the thing is that BIOS allows me only too add 2.85v maximum.
    Im trying to find a newer version of BIOS version 3.1 if there is any....
    Here: http://www.techpowerup.com/articles/other/111
    v5.0 Beta 4 allows to give 3.10V to the memory but i don´t think it´s going to help you, you probably have the CBBID issue.

  • MSI K8N SLI Platinum vs 1.5TB Western Digital

    Hi Everyone,
    I have recently been having some issues with my K8N SLI platinum and hoping I could get some help on resolving the issue.
    For the past 2 years i have been running the machine with multiple SATA drives (160GB{boot} and 300GB) and have now tried to add an additional 1.5TB WD and have encountered some problems. If i put my 1.5TB into a USB enclosure and then connect it to my machine it is recognized perfectly and I am able to write and read from the drive, However if i put it into my machine as a secondary HDD my computer fails to boot.
    First when i put the drive in my computer no longer boots to windows. It gets to post and loads the drives (including the new drive) and then wont go any further. PC seems to stall and wont allow me to get to the BIOS.
    I boot up the machine without the drive connected and go into the BIOS and then reconnect the drive. If i do a HDD Scan on SATA3 then the drive will be recognized (however capacity is only 136GB).
    My first thoughts were that it was a bios related issue so I have updated the Bios to the latest (3.C according to LiveUpdate) and am still having the same issue. Im not really sure where to go from now. 
    Any help would be greatly appreciated.
    Thanks for your time.
    Tim

    Hello! Please say what your system looks like. Include what PSU you are using.
    Try a different cable.
    Jumper the disk to SATA 1.
    Try the disk in a different system.

  • MOVED: K8N SLI PLATINUM QUESTIONS

    This topic has been moved to Overclockers & Modding Corner.
    K8N SLI PLATINUM QUESTIONS

    Okay  finally i overclocked a bit (i am not really in the overclocking business)
    With Bios defaults settings without touching anything else i raised FSB to 220 MHz resulting to a 2.2 GHz CPU operating frequency a nice 10% overclock    (of course  i have disabled spread spectrum in bios) reaching that way the Athlon 64 3500+ .
    Every thing seemed rock - stable!!..
    However, when i tried to shut down the machine,  i got a nice BSOD (Black screen of death) HDD light remained on . As far as i know the board is locking PCI-E , so graphics card and SATA drive should not causing the problem here.
    So i raised the CPU core voltage up to 5% and oualla!! Rock stable ( 3 Hours Prime 95)
    ... did not try to rise chipset voltage or memory voltage (is set to 2.7 volts by memory SPD) since this was not necessary in my case. Might try some more overclocking in the future but right now i am happy with it and just will sit back and enjoy     
    There is a guy who succeeded in rising FSB to 358!!! Mhz with this board (well almost) he advices just not to enable Aggressive memory timings...
    here
    Anyway, Thanks for the tips guys

  • MSI k8N SLI Platinum - dead??

    Hello,
    I have started the PC as per usual. Pushed the power button... nothing. Then again... nothing. Then I swithed off from the switch near the mains entry. and switched on... PC started however I get nothing on the screen. No beeps.
    I have an Antec Truecontrol 2.0 power supply, an MSI K8N SLI Platinum (socket 939) with AMD Athlon, 2 GB Corsair TWINX Ram, three HDDS SATA, Raptor 75GB as Primary (C:) and another two WDS. Video Card: BFG 7800GTX+ 256MB OC, PCI - Express.
    System has functioned Ok for three and a half years at least. I have replaced the Northbridge Fan from the beginning with a Blue heatsink - I believe Zalman. No temp issues. No overclocking, I am not using any commander modes etc etc.
    When I look at the D-Bracket I get Memory Init Error (RED-GReen-Red-Red). I am pretty sure it is not the RAM. I pulled the RAM, used only one stick... same error.
    I pulled the video card out. Then interestingly the system reaches the phase just before booting and the D_Bracket shows Floppy Init error (Green-Red-Green-Green). I tried moving the video card to the second PCI -ex - I also reach the Floppy Error point. I put in a crappy PIC-Ex video card - I reach the same Floppy init point - the floppy actually seeks but does not try to read. Unfort I forgot where I put the Monitor adapter thingy so I can;t check if I get anything on the screen with the crappy PCI-Ex video card. Will get it... soon...
    I have a hard time determining whether it is the Video card or the mainboard. I have pulled the battery out, left overnight, pushed the BIOS reset... nothing helped. With Video Card in PCI-Ex slot 1, I get the memory init error. With the card in PCI-Ex slot 2 or with no card or with crappy PCI-Ex, I get to the Floppy Init point.
    Could it be that at that point I would be getting a VGA error that I cannot see on the screen ? Why then NO BEEPS? Does this Mobo model not beep, just uses the D-Bracket?
    It is important - if it is the mobo I am done for, I have to buy Mobo, RAM, CPU... $1,000. If it is the Video card I may find something 1 slot wide and similar to the BFG ...
    Can anyone help narrow this please ?
    BTW on the screen I get NOTHING, if I pull out the cable the monitor says - check connection, if I plug it in the monitor goes to power saving.
    Thank you Heaps

    Those Corsairs you have need more voltage to start if I'm not mistaken.
    Found out what the prob was - the BFG 7800GTX was DEAD. RMA-ed the card. the MSI Mobo is Ok

  • MSI K8N SLI Platinum and 4x512 DDR

    Hello everybody,
    My problem is with a 2nd kit of 2x512 MB DDR I bought recently. I had a pair of  Kingston KHX3200ULK2 512 MB and unfortunately this model was discontinued, so I got another 2x512 MB DDR, this time Geil UltraX which should work @ 5-2-2-2-1T.
    When leaving everything on auto, the motherboard sets the 4 modules at DDR333 with the tightest timing. I want to run them in DDR400, so I set them up manually @ 5-2-2-2-2T. In this config, everything is unstable. Sometimes the system doesn't boot, sometimes I get blue screens, etc.
    Can somebody help me with some ideas ? The system appears to run stable with timings setup at 6-4-4-2-2T, but I really paid a lot on those modules and I'd like to squeeze the most out of them.
    Thanks in advance

  • Any known problems: MSI K8N SLI Platinum + seagate 7200.9 sata2 hdd?

    Hi all.
    I planning to buy Seagate sataII 7200.9 250GB drive (model: ST3250824AS) very soon (finally they are in stock in my city), but first i want to know is there any incompatibility issues or other problems with such combination - MSI K8N SLI Platinum + seagate 7200.9 series hdd.
    I don't have any experience with sata2 drives yet. Currently i'm using seagate 7200.7 120GB IDE hdd.
    I don't plan use RAID or use that new 7200.9 drive in combination with current 7200.7 drive (will use current hdd in other pc).
    Any tips/experience would be great.

    Seagate SATA II 7200.9 250GB drive (model: ST3250824AS) has both 3 G/bps speed and NCQ (Native Command Queuing) most all MB’s with the nVidia Chipsets using the nForce4 chip will have problems.  If they are not using RAID and you reduce the speed to 1.5 G/bps with a single drive you maybe able to get it to work.  Personally, I know the MS-7125 and MS-7220 both will not run RAID with those to motherboards.
    I have been battling with MSI and ASUS over this problem sense November and they have not come up with a fix.  Problem involved BIOS and RAID Controller Driver for the chipset.  Most MSI motherboards latest BIOS have fixed the BIOS half of the problem.  There is an unreleased 32-bit driver for Windows, but nothing for Windows XP 64.

  • 2nd K8N SLi Platinum motherboard just died

    Hope somebody else has experienced this - now on my 3rd board. A bit about my system:
    Msi K8N SLi Platinum motherboard
    2 x Seagate Barracuda ST3200822AS 200Gb Hard disk
    Antec PSU True Blue 480w
    1 x AMD (Winchester) Athlon 64bit 3200+ CPU
    OCZ Dual Channel Kit 2x512MB DDR400 Ram
    128MB Gigabyte GV NX66T128VP Graphics Card
    Running MCE 2005
    I built my first system running Media Center 2005 a few months back. Very stable. Used to put it into S3 sleep mode each evening and wake up the next day. Never any problems. CPU temp ran about 47degC. Never did anything stressful on it, no games just watched tv with a tuner card and played mp3s.
    One day it wouldn't wake up, wouldn't post, no beeps nothing. cpu fan spun briefly (2 secs) and died. I stripped it down to bare essentials (1 stick ram, cpu). Tested PSU - fine. Tried out of case, again no joy, so I RMAed. Put it down to a bad board.
    So I installed the new board - it worked fine. Must have been a bad board. Great! It ran for another month and the same thing happened, it just would wake up one day! Now I'm worried, am I doing something wrong with these boards, are they getting too hot? How come they fail when they are switched off? Is it a bios thing? - I tried resetting the Cmos, no joy there.
    Any way that I can update the bios when they are in this state?
    Any ideas - cheers Richard

    richardwilshire...here is a list of many potential non-compliant APM features you may want to look at, and note that these are carry-overs from Windows 2000, the foundation of WinXP:
    Key APM Components and What They Do
    APM BIOS: Placed in ROM or flash by the OEM. Does most of the real work of powering the system on and off. The operating system can call the BIOS, and it either works or it doesn't; its operation is opaque to the operating system. The APM BIOS must be turned on using the BIOS setup utility for APM to work. If the APM BIOS is unstable, it may be necessary to turn the APM BIOS off using the BIOS setup utility, in addition to turning off Windows 2000 APM support. The APM BIOS should be configured such that timeouts are either turned off or set for the longest period possible, so that the operating system can control timeouts instead of the APM BIOS.
    Ntdetect.com: It detects whether the APM BIOS is present before booting the operating system, determines whether Windows 2000 can use it, and reports the results of detection in the registry.
    NtLdr: Restarts APM upon resume from hibernate, if APM was active before hibernation.
    Ntapm.sys: A Windows 2000 driver that hooks the system and the APM BIOS together. It includes certain system operations for dispatch to the APM BIOS, and it polls APM BIOS events and status. Note than when the APM BIOS presents an event (such as suspend or power off), Ntapm.sys catches this, and then issues an NtInitiatePowerAction call, which tells the operating system to respond appropriately. At the end, the Windows 2000 power manager calls into the HAL, which calls back into Ntapm.sys, which calls the APM BIOS. In this process, almost all operating system and driver power code is the same between APM and ACPI.
    Hal.dll: Windows 2000 APM support works only with Halx86, which is the only HAL to have the hooks needed to call into Ntapm.sys. It's also the only HAL relevant to important APM machines in the market.
    Apmbatt.sys: This emulates a battery unit so the system battery status code can work.
    Power Applet: The Control Panel applet that allows the user to enable or disable APM support on a computer. This is the only supported way to turn operating system APM support on or off.
    Biosinfo.inf: Windows 2000 file that lists machines on the Autoenable APM list and the Disable APM list, and also lists the BIOS detection sequences used to match them.
    Key Elements in the Registry
    Ntdetect Reporting. The data about APM that is discovered by Ntdetect.com is reported in the registry using a Multi-function adapter (MFA) entry in the system description of the hardware tree. To find this, look in HKEY_LOCAL_MACHINE\ hardware\ description\ system\ multifunctionadapter.
    There will be a set of keys there named 0, 1, 2, 3, etc. Each of them will have value entries named Component Information, Configuration Data, Identifier, and so on. Find the key whose Identifier entry == "APM". The "Configuration Data" entry of that key will contain the data on APM found and reported by Ntdetect.com. If the key is absent, then APM was not found. The contents of this value entry are reported in sdk\inc\ntapmsdk.h.
    Running Apmstat.exe -v will dump this structure, for machines where it's relevant. For machines where it's not relevant (multiprocessors, not x86, not halx86, ACPI is on, and so on), Apmstat.exe will report that.
    Biosinfo vs. Machine-Specific Info. The results of machine-specific detection versus Biosinfo.inf are stored in HKEY_LOCAL_MACHINE\ System\ CurrentControlSet\ Control\ BIOSInfo\ APM. If the "Attributes" value is 1, the machine's APM BIOS is "known good" and the machine is on the Autoenable APM list. If the value 2, the machine's APM BIOS is "known bad" and the machine is on the Disable APM list. Otherwise, the machine is neutral.
    Running apmstat will report whether the APM BIOS is known to be good, known to be bad, or is neutral.
    HAL Reporting. If the HAL is Halx86.dll, the registry key HKEY_LOCAL_MACHINE\ System\ CurrentControlSet\ Control\ ApmLegalHal will have a value entry present with data of 1.
    Running apmstat will report if this is not the case.
    ACPI Reporting. If the machine is an ACPI machine, there will be a services entry for ACPI under (HKLM\System\currentcontrolset\services\ACPI) with value Start == 0. This is telling the system to load and run Acpi.sys at phase 0. If this is not present, the machine is not being run as an ACPI machine, even if, perhaps, it should be.
    Running apmstat will report a machine as an ACPI machine if it sees Acpi.sys has Start == 0.
    UI Elements
    Power Applet APM Tab. The Control Panel includes a Power applet. If the APM is installed at all (enabled or disabled), there will be an APM tab in this applet. You can turn APM on and off by checking the box in this tab. This is the only recommended and supported way to do that. Turning APM on is an on-the-fly Plug and Play action; turning it off requires a reboot. If the tab is absent, it's an ACPI machine, an APM Disabled machine, or the machine simply doesn't have APM.
    Standby on Shutdown Menu. If APM is turned on, there will be a Standby entry under the Shutdown option when the user presses CTRL+ALT+DEL. There may also be a Hibernate entry, which is a separate function. (Hibernate can work even if neither APM nor ACPI are present.) Standby under APM has the same use as under ACPI.
    Battery Status Icon. If the battery display is turned on in the Control Panel Power applet, there will be a Battery Status icon on the system tray, which works about the same as for ACPI. Note that an APM machine always reports a single composite battery, regardless of how many are present or what the machine reports. (Windows 2000 uses the unified/composite number, because this is thought to be more reliable on a wide range of APM BIOSes, and is simpler.)
    Power Button. On most APM machines, the power button, a sleep button, or the like, can suspend the machine (place on standby). Most require the power button to resume, though at least one will come back with a keyboard touch. Windows 2000 APM does not support custom power buttons.
    Tools
    Apmstat.exe: As of Windows 2000 RC1, Apmstat.exe is included in the support directory on the Windows 2000 product CD. Support personnel and expert users can run this utility to determine status.
    BIOS Setup Utility. Essentially all APM machines will have some sort of machine setup/configuration screen, usually accessed at boot by pressing ESC, DEL, F1, F2, or F10. Support personnel and expert users may be able to improve system behavior by changing or disabling APM options.
    Note: Be warned that some APM BIOSes will turn themselves off if all timers are disabled. In this case, it's best to set all timers to some long timeout value.
    APM BIOS and Kernel Debugger. Some APM BIOSes will refuse to suspend if the kernel debugger is active on one of the system COM ports.
    Event log. If an APM_SETPOWER call fails (that is, a standby/suspend fails at the APM BIOS interface), then Ntapm.sys will write a record into the system event log, with data reporting that this happened and whatever error code the APM BIOS returned. This information is sometimes useful if a machine is refusing to suspend because of activity on some port that isn't obvious to the user.
    NOTES:
    • APM support is not allowed on server products. This means that the APM tab will not appear and that there is no APM support in Windows 2000 Advanced Server or in Windows 2000 Datacenter.
    • APM will not hook up the standby vector on machines that do not have batteries. This means that on machines that do not have batteries, standby will not appear as an option on the Shutdown list, and will not be available as an operation.
    • Hibernate is independent of APM or ACPI; hibernate can be used on machines that do not have either APM or ACPI.
    • To get the battery status icon, you must turn it on with the Power applet in the control panel.
    • To get hibernate, you must turn it on with the Power applet in the control panel.
    Suggestions for Problem Resolution
    The following provides guidelines for support personnel or expert users who are troubleshooting APM support on a system running Windows 2000.
    1.
     Make sure the user has APM turned on, hibernate turned on, and the battery icon turned on.
    2.
     Make sure that APM BIOS screen blanking is turned off. This will often make the system seem to behave badly when problem is only that the screen is black. (Use a screen saver of BLANK to get the right effect.)
    3.
     Run Apmstat.exe. Its output will often make the issue obvious (trying to run APM on a multiple-processor machine, for example).
    4.
    If the machine is a desktop, it will rarely run APM well, but you can get 90 percent of the value by using hibernate, which does not require either APM or ACPI to work.
    5. If Windows 2000 APM has been turned off, and the machine is still not stable, try turning off the APM BIOS itself in the machine's setup     screen.
    6.
     Some machines will work better with Windows 2000 APM turned on, because this puts the operating system more in sync with the system's APM BIOS.
